Yes. paperI am working on, but the general idea is that each sender maintains alist of all messages they have sent, which has a version numberassociated with it in the Rhizome Manifest file. If a recipientalready has that version of the file, then it doesn't refetch it.Else, it refetches the file. We have a mechanism we have planned butnot yet implemented where only the new part of the file gets fetched,and also that expires the old part of the file that contains alreadydelivered messages, together working to minimise network traffic. they know the message was delivered, which also means thatthey can advance the beginning point in their message log to excludethe received message (assuming there are no others before it that arestill pending). That goes out in the form of an updated manifest fromthe sender. When the recipient sees this new manifest that doesn'tinclude the original message, it can deduce that the message receiptwas acknowledged, and it can advance it's starting point in itsmessage file in the same way. All this means that after a message isreceived, it will phase out from being carried by devices on the mesh. We are also planning various scope limiting features to stop messagesflooding too far or for too long. Paul. On Jan 1 2002, 8:57 pm, "Paul" wrote:

It is my understanding that if the target batphone is off the mesh, the message will log with any available phone it can find on the mesh and the 1st phone to find the target will deliver. Is there any intelligence in the network that informs a second phone finding the target that the message has been delivered ? Likewise, will a 'mule' phone update the mesh when it comes back in range to say ' I delivered ' all OK ! and delete the message on other potential mules in the mesh ?

Hello,

In this prototype we don't have security in place, but the messages will be encrypted using public-private crypto such that only the recipient can receive the message. We also offer the option of encrypting the recipient so that there is confidentiality as to who the recipient is -- although that protection is only partial, as it wouldn't take too much analysis to observe the patterns of receiving and sending messages to make some well informed guesses about social network structure.

Paul.

for some details, video and cartoon to explain a little of how it works. I am also working on a white paper that describes it in much more detail.

Sounds nice in theory, but what about message security....... if someone elses phone contains the message as a courier device could it not be intercepted and read by a devious user?
